#include "defs.h"
Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

#include "event-top.h"
PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

Introduce interpreter factories If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

class cli_interp final : public cli_interp_base
Introduce interpreter factories If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

C++-fy struct interp/cli_interp/tui_interp/mi_interp - The interp->data field disappears, since we can put data in the interpreter directly now.

/* The ui_out for the console interpreter. */
Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Introduce interpreter factories If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

C++-fy struct interp/cli_interp/tui_interp/mi_interp - The interp->data field disappears, since we can put data in the interpreter directly now. The "init" method remains in place, but it now returns void. - A few places check if the interpreter method is NULL before calling it, and also check whether the method returns true/false. For some of those methods, all current implementations always return true. In those cases, this commit makes the C++-fied method return void instead and cleans up the callers.

Emit inferior, thread and frame selection events to all UIs With this patch, when an inferior, thread or frame is explicitly selected by the user, notifications will appear on all CLI and MI UIs. When a GDB console is integrated in a front-end, this allows the front-end to follow a selection made by the user ont he CLI, and it informs the user about selection changes made behind the scenes by the front-end. This patch addresses PR gdb/20487. In order to communicate frame changes to the front-end, this patch adds a new field to the =thread-selected event for the selected frame. The idea is that since inferior/thread/frame can be seen as a composition, it makes sense to send them together in the same event. The vision would be to eventually send the inferior information as well, if we find that it's needed, although the "=thread-selected" event would be ill-named for that job. Front-ends need to handle this new field if they want to follow the frame selection changes that originate from the console. The format of the frame attribute is the same as what is found in the *stopped events. Here's a detailed example for each command and the events they generate: thread ------ 1. CLI command: thread 1.3 MI event: =thread-selected,id="3",frame={...} 2. MI command: -thread-select 3 CLI event: [Switching to thread 1.3 ...] 3. MI command (CLI-in-MI): thread 1.3 MI event/reply: &"thread 1.3\n" ~"#0 child_sub_function () ... =thread-selected,id="3",frame={level="0",...} ^done frame ----- 1. CLI command: frame 1 MI event: =thread-selected,id="3",frame={level="1",...} 2. MI command: -stack-select-frame 1 CLI event: #1 0x00000000004007f0 in child_function... 3. MI command (CLI-in-MI): frame 1 MI event/reply: &"frame 1\n" ~"#1 0x00000000004007f9 in ..." =thread-selected,id="3",frame={level="1"...} ^done inferior -------- Inferior selection events only go from the console to MI, since there's no way to select the inferior in pure MI. 1. CLI command: inferior 2 MI event: =thread-selected,id="3" Note that if the user selects an inferior that is not started or exited, the MI doesn't receive a notification. Since there is no threads to select, the =thread-selected event does not apply... 2. MI command (CLI-in-MI): inferior 2 MI event/reply: &"inferior 2\n" ~"[Switching to inferior 2 ...]" =thread-selected,id="4",frame={level="0"...} ^done Internal implementation detail: this patch makes it possible to suppress notifications caused by a CLI command, like what is done in mi-interp.c. This means that it's now possible to use the add_com_suppress_notification function to register a command with some event suppressed. It is used to implement the select-frame command in this patch. The function command_notifies_uscc_observer was added to extract the rather complicated logical expression from the if statement. It is also now clearer what that logic does: if the command used by the user already notifies the user_selected_context_changed observer, there is not need to notify it again. It therefore protects again emitting the event twice. No regressions, tested on ubuntu 14.04 x86 with target boards unix and native-extended-gdbserver. gdb/ChangeLog: YYYY-MM-DD Antoine Tremblay <antoine.tremblay@ericsson.com> YYYY-MM-DD Simon Marchi <simon.marchi@ericsson.com> PR gdb/20487 * NEWS: Mention new frame field of =thread-selected event. * cli/cli-decode.c (add_cmd): Initialize c->suppress_notification.

Make the intepreters output to all UIs When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ...

But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

/* See cli-interp.h.
Breakpoint hits should always be mirrored to a console. Deciding
what to mirror to a console wrt to breakpoints and random stops
gets messy real fast. E.g., say "s" trips on a breakpoint. We'd
clearly want to mirror the event to the console in this case. But
what about more complicated cases like "s&; thread n; s&", and one
of those steps spawning a new thread, and that thread hitting a
breakpoint? It's impossible in general to track whether the thread
had any relation to the commands that had been executed. So we
just simplify and always mirror breakpoints and random events to
all consoles.
OTOH, we should print the source line to the console when stepping
or other similar commands, iff the step was started by that console
(or in MI's case, by a console command), but not if it was started
with MI's -exec-step or similar. */

Push thread->control.command_interp to the struct thread_fsm I noticed that if we step into an inline function, step_1 never reaches proceed, and thus nevers sets the thread's tp->control.command_interp. Because of that, should_print_stop_to_console fails to determine that is should print stop output to the console. The fix is to set the thread's command_interp earlier. However, I realized that we can move that field to the thread_fsm, given that its lifetime is exactly the same as thread_fsm. So the patch plumbs all fsms constructors to take the command interp and store it in the thread_fsm. We can see the fix in action, with e.g., the gdb.opt/inline-cmds.exp test, and issuing a step when stopped at line 67: &"s\n" ^running *running,thread-id="all" (gdb) ~"67\t result = func2 ();\n" *stopped,reason="end-stepping-range",frame={addr="0x00000000004004d0",func="main",args=[],file="/home/pedro/gdb/mygit/src/gdb/testsuite/gdb.opt/inline-cmds.c",fullname="/home/pedro/gdb/mygit/src/gdb/testsuite/gdb.opt/inline-cmds.c",line="67"},thread-id="1",stopped-threads="all",core="0" (gdb) s &"s\n" ^running *running,thread-id="all" (gdb) + ~"func2 () at /home/pedro/gdb/mygit/src/gdb/testsuite/gdb.opt/inline-cmds.c:67\n" + ~"67\t result = func2 ();\n" *stopped,reason="end-stepping-range",frame={addr="0x00000000004004d0",func="func2",args=[],file="/home/pedro/gdb/mygit/src/gdb/testsuite/gdb.opt/inline-cmds.c",fullname="/home/pedro/gdb/mygit/src/gdb/testsuite/gdb.opt/inline-cmds.c",line="67"},thread-id="1",stopped-threads="all",core="0" (gdb) (The inline-cmds.exp command is adjusted to exercise this.)

/* Observers for several run control events. If the interpreter is
quiet (i.e., another interpreter is being run with
interpreter-exec), print nothing. */
Replace "struct continuation" mechanism by something more extensible This adds an object oriented replacement for the "struct continuation" mechanism, and converts the stepping commands (step, next, stepi, nexti) and the "finish" commands to use it. It adds a new thread "class" (struct thread_fsm) that contains the necessary info and callbacks to manage the state machine of a thread's execution command. This allows getting rid of some hacks. E.g., in fetch_inferior_event and normal_stop we no longer need to know whether a thread is doing a multi-step (e.g., step N). This effectively makes the intermediate_continuations unused -- they'll be garbage collected in a separate patch. (They were never a proper abstraction, IMO. See how fetch_inferior_event needs to check step_multi before knowing whether to call INF_EXEC_CONTINUE or INF_EXEC_COMPLETE.) The target async vs !async uiout hacks in mi_on_normal_stop go away too. print_stop_event is no longer called from normal_stop. Instead it is now called from within each interpreter's normal_stop observer. This clears the path to make each interpreter print a stop event the way it sees fit. Currently we have some hacks in common code to differenciate CLI vs TUI vs MI around this area. The "finish" command's FSM class stores the return value plus that value's position in the value history, so that those can be printed to both MI and CLI's streams. This fixes the CLI "finish" command when run from MI -- it now also includes the function's return value in the CLI stream: (gdb) ~"callee3 (strarg=0x400730 \"A string argument.\") at src/gdb/testsuite/gdb.mi/basics.c:35\n" ~"35\t}\n" +~"Value returned is $1 = 0\n" *stopped,reason="function-finished",frame=...,gdb-result-var="$1",return-value="0",thread-id="1",stopped-threads="all",core="0" -FAIL: gdb.mi/mi-cli.exp: CLI finish: check CLI output +PASS: gdb.mi/mi-cli.exp: CLI finish: check CLI output gdb/ChangeLog: 2015-09-09 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_OBS): Add thread-fsm.o. * breakpoint.c (handle_jit_event): Print debug output.

SWITCH_THRU_ALL_UIS ()
Replace "struct continuation" mechanism by something more extensible This adds an object oriented replacement for the "struct continuation" mechanism, and converts the stepping commands (step, next, stepi, nexti) and the "finish" commands to use it. It adds a new thread "class" (struct thread_fsm) that contains the necessary info and callbacks to manage the state machine of a thread's execution command. This allows getting rid of some hacks. E.g., in fetch_inferior_event and normal_stop we no longer need to know whether a thread is doing a multi-step (e.g., step N). This effectively makes the intermediate_continuations unused -- they'll be garbage collected in a separate patch. (They were never a proper abstraction, IMO. See how fetch_inferior_event needs to check step_multi before knowing whether to call INF_EXEC_CONTINUE or INF_EXEC_COMPLETE.) The target async vs !async uiout hacks in mi_on_normal_stop go away too. print_stop_event is no longer called from normal_stop. Instead it is now called from within each interpreter's normal_stop observer. This clears the path to make each interpreter print a stop event the way it sees fit. Currently we have some hacks in common code to differenciate CLI vs TUI vs MI around this area. The "finish" command's FSM class stores the return value plus that value's position in the value history, so that those can be printed to both MI and CLI's streams. This fixes the CLI "finish" command when run from MI -- it now also includes the function's return value in the CLI stream: (gdb) ~"callee3 (strarg=0x400730 \"A string argument.\") at src/gdb/testsuite/gdb.mi/basics.c:35\n" ~"35\t}\n" +~"Value returned is $1 = 0\n" *stopped,reason="function-finished",frame=...,gdb-result-var="$1",return-value="0",thread-id="1",stopped-threads="all",core="0" -FAIL: gdb.mi/mi-cli.exp: CLI finish: check CLI output +PASS: gdb.mi/mi-cli.exp: CLI finish: check CLI output gdb/ChangeLog: 2015-09-09 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_OBS): Add thread-fsm.o. * breakpoint.c (handle_jit_event): Print debug output.

Make the intepreters output to all UIs When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

SWITCH_THRU_ALL_UIS ()
Make the intepreters output to all UIs When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

SWITCH_THRU_ALL_UIS ()
Make the intepreters output to all UIs When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

SWITCH_THRU_ALL_UIS ()
Make the intepreters output to all UIs When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

PR gdb/13860 - Make MI sync vs async output (closer to) the same. Ignoring expected and desired differences like whether the prompt is output after *stoppped records, GDB MI output is still different in sync and async modes. In sync mode, when a CLI execution command is entered, the "reason" field is missing in the *stopped async record. And in async mode, for some events, like program exits, the corresponding CLI output is missing in the CLI channel. Vis, diff between sync vs async modes: run ^running *running,thread-id="1" (gdb) ... - ~"[Inferior 1 (process 15882) exited normally]\n" =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" si ... (gdb) ~"0x000000000045e033\t29\t memset (&args, 0, sizeof args);\n" - *stopped,frame=...,thread-id="1",stopped-threads="all",core="0" + *stopped,reason="end-stepping-range",frame=...,thread-id="1",stopped-threads="all",core="0" (gdb) In addition, in both cases, when a MI execution command is entered, and a breakpoint triggers, the event is sent to the console too. But some events like program exits have the CLI output missing in the CLI channel: -exec-run ^running *running,thread-id="1" (gdb) ... =thread-exited,id="1",group-id="i1" =thread-group-exited,id="i1",exit-code="0" - *stopped + *stopped,reason="exited-normally" We'll want to make background commands always possible by default. IOW, make target-async be the default. But, in order to do that, we'll need to emulate MI sync on top of an async target. That means we'll have yet another combination to care for in the testsuite. Rather than making the testsuite cope with all these differences, I thought it better to just fix GDB to always have the complete output, no matter whether it's in sync or async mode. This is all related to interpreter-exec, and the corresponding uiout switching. (Typing a CLI command directly in MI is shorthand for running it through -interpreter-exec console.) In sync mode, when a CLI command is active, normal_stop is called when the current interpreter and uiout are CLI's. So print_XXX_reason prints the stop reason to CLI uiout (only), and we don't show it in MI. In async mode the stop event is processed when we're back in the MI interpreter, so the stop reason is printed directly to the MI uiout. Fix this by making run control event printing roughly independent of whatever is the current interpreter or uiout. That is, move these prints to interpreter observers, that know whether to print or be quiet, and if printing, which uiout to print to. In the case of the console/tui interpreters, only print if the top interpreter. For MI, always print. Breakpoint hits / normal stops are already handled similarly -- MI has a normal_stop observer that prints the event to both MI and the CLI, though that could be cleaned up further in the direction of this patch. This also makes all of: (gdb) foo and (gdb) interpreter-exec MI "-exec-foo" and (gdb) -exec-foo and (gdb) -interpreter-exec console "foo" print as expected.

Make display_gdb_prompt CLI-only. Enabling target-async by default will require implementing sync execution on top of an async target, much like foreground command are implemented on the CLI in async mode. In order to do that, we will need better control of when to print the MI prompt. Currently the interp->display_prompt_p hook is all we have, and MI just always returns false, meaning, make display_gdb_prompt a no-op. We'll need to be able to know to print the MI prompt in some of the conditions that display_gdb_prompt is called from the core, but not all. This is all a litte twisted currently. As we can see, display_gdb_prompt is really CLI specific, so make the console interpreters (console/tui) themselves call it. To be able to do that, and add a few different observers that the interpreters can use to distinguish when or why the the prompt is being printed: #1 - one called whenever a command is cancelled due to an error. #2 - another for when a foreground command just finished. In both cases, CLI wants to print the prompt, while MI doesn't. MI will want to print the prompt in the second case when in a special MI mode. The display_gdb_prompt call in interp_set made me pause. The comment there reads: /* Finally, put up the new prompt to show that we are indeed here. Also, display_gdb_prompt for the console does some readline magic which is needed for the console interpreter, at least... */ But, that looks very much like a no-op to me currently: - the MI interpreter always return false in the prompt hook, meaning actually display no prompt. - the interpreter used at that point is still quiet. And the console/tui interpreters return false in the prompt hook if they're quiet, meaning actually display no prompt. The only remaining possible use would then be the readline magic. But whatever that might have been, it's not reacheable today either, because display_gdb_prompt returns early, before touching readline if the interpreter returns false in the display_prompt_p hook.

In order to do that, we will need better control of when to print the MI prompt. Currently the interp->display_prompt_p hook is all we have, and MI just always returns false, meaning, make display_gdb_prompt a no-op. We'll need to be able to know to print the MI prompt in some of the conditions that display_gdb_prompt is called from the core, but not all. This is all a litte twisted currently. As we can see, display_gdb_prompt is really CLI specific, so make the console interpreters (console/tui) themselves call it. To be able to do that, and add a few different observers that the interpreters can use to distinguish when or why the the prompt is being printed: #1 - one called whenever a command is cancelled due to an error. #2 - another for when a foreground command just finished. In both cases, CLI wants to print the prompt, while MI doesn't. MI will want to print the prompt in the second case when in a special MI mode. The display_gdb_prompt call in interp_set made me pause. The comment there reads: /* Finally, put up the new prompt to show that we are indeed here. Also, display_gdb_prompt for the console does some readline magic which is needed for the console interpreter, at least... */ But, that looks very much like a no-op to me currently: - the MI interpreter always return false in the prompt hook, meaning actually display no prompt. - the interpreter used at that point is still quiet. And the console/tui interpreters return false in the prompt hook if they're quiet, meaning actually display no prompt. The only remaining possible use would then be the readline magic. But whatever that might have been, it's not reacheable today either, because display_gdb_prompt returns early, before touching readline if the interpreter returns false in the display_prompt_p hook.

Emit inferior, thread and frame selection events to all UIs With this patch, when an inferior, thread or frame is explicitly selected by the user, notifications will appear on all CLI and MI UIs. When a GDB console is integrated in a front-end, this allows the front-end to follow a selection made by the user ont he CLI, and it informs the user about selection changes made behind the scenes by the front-end. This patch addresses PR gdb/20487. In order to communicate frame changes to the front-end, this patch adds a new field to the =thread-selected event for the selected frame. The idea is that since inferior/thread/frame can be seen as a composition, it makes sense to send them together in the same event. The vision would be to eventually send the inferior information as well, if we find that it's needed, although the "=thread-selected" event would be ill-named for that job. Front-ends need to handle this new field if they want to follow the frame selection changes that originate from the console. The format of the frame attribute is the same as what is found in the *stopped events. Here's a detailed example for each command and the events they generate: thread ------ 1. CLI command: thread 1.3 MI event: =thread-selected,id="3",frame={...} 2. MI command: -thread-select 3 CLI event: [Switching to thread 1.3 ...] 3. MI command (CLI-in-MI): thread 1.3 MI event/reply: &"thread 1.3\n" ~"#0 child_sub_function () ... =thread-selected,id="3",frame={level="0",...} ^done frame ----- 1. CLI command: frame 1 MI event: =thread-selected,id="3",frame={level="1",...} 2. MI command: -stack-select-frame 1 CLI event: #1 0x00000000004007f0 in child_function... 3. MI command (CLI-in-MI): frame 1 MI event/reply: &"frame 1\n" ~"#1 0x00000000004007f9 in ..." =thread-selected,id="3",frame={level="1"...} ^done inferior -------- Inferior selection events only go from the console to MI, since there's no way to select the inferior in pure MI. 1. CLI command: inferior 2 MI event: =thread-selected,id="3" Note that if the user selects an inferior that is not started or exited, the MI doesn't receive a notification. Since there is no threads to select, the =thread-selected event does not apply... 2. MI command (CLI-in-MI): inferior 2 MI event/reply: &"inferior 2\n" ~"[Switching to inferior 2 ...]" =thread-selected,id="4",frame={level="0"...} ^done Internal implementation detail: this patch makes it possible to suppress notifications caused by a CLI command, like what is done in mi-interp.c. This means that it's now possible to use the add_com_suppress_notification function to register a command with some event suppressed. It is used to implement the select-frame command in this patch. The function command_notifies_uscc_observer was added to extract the rather complicated logical expression from the if statement. It is also now clearer what that logic does: if the command used by the user already notifies the user_selected_context_changed observer, there is not need to notify it again. It therefore protects again emitting the event twice.

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler! Aborted (core dumped) The fix for that was to add an interp_proc method to query the interpreter whether it actually supports editing.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler! Aborted (core dumped) The fix for that was to add an interp_proc method to query the interpreter whether it actually supports editing.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

Class-ify ui_out This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

cli_interp_base::supports_command_editing ()
Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

Normalize TRY_CATCH exception handling block This normalizes some exception catch blocks that check for ex.reason to look like this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ALL) { ... } if (ex.reason < 0) { ... } ~~~ This is a preparation step for running a script that converts all TRY_CATCH uses to look like this instead: ~~~ TRY { ... } CATCH (ex, RETURN_MASK_ALL) { ... } END_CATCH ~~~ The motivation for that change is being able to reimplent TRY/CATCH in terms of C++ try/catch. This commit makes it so that: - no condition other than ex.reason < 0 is checked in the if predicate - there's no "else" block to check whether no exception was caught - there's no code between the TRY_CATCH (TRY) block and the 'if (ex.reason < 0)' block (CATCH). - the exception object is no longer referred to outside the if/catch block. Note the local volatile exception objects that are currently defined inside functions that use TRY_CATCH will disappear. In cases it's more convenient to still refer to the exception outside the catch block, a new non-volatile local is added and copy to that object is made within the catch block. The following patches should make this all clearer. gdb/ChangeLog: 2015-03-07 Pedro Alves <palves@redhat.com> * amd64-tdep.c (amd64_frame_cache, amd64_sigtramp_frame_cache) (amd64_epilogue_frame_cache): Normal exception handling code. * break-catch-throw.c (check_status_exception_catchpoint) (re_set_exception_catchpoint): Ditto. * cli/cli-interp.c (safe_execute_command): * cli/cli-script.c (script_from_file): Ditto. * compile/compile-c-symbols.c (generate_c_for_for_one_variable): Ditto. * compile/compile-object-run.c (compile_object_run): Ditto. * cp-abi.c (baseclass_offset): Ditto. * cp-valprint.c (cp_print_value): Ditto. * exceptions.c (catch_exceptions_with_msg): * frame-unwind.c (frame_unwind_try_unwinder): Ditto. * frame.c (get_frame_address_in_block_if_available): Ditto. * i386-tdep.c (i386_frame_cache, i386_epilogue_frame_cache) (i386_sigtramp_frame_cache): Ditto. * infcmd.c (post_create_inferior): Ditto. * linespec.c (parse_linespec, find_linespec_symbols): * p-valprint.c (pascal_object_print_value): Ditto. * parse.c (parse_expression_for_completion): Ditto. * python/py-finishbreakpoint.c (bpfinishpy_init): Ditto. * remote.c (remote_get_noisy_reply): Ditto. * s390-linux-tdep.c (s390_frame_unwind_cache): Ditto. * solib-svr4.c (solib_svr4_r_map): Ditto.

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here.

Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist.

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here.

CATCH (exception, RETURN_MASK_ALL)
Normalize TRY_CATCH exception handling block This normalizes some exception catch blocks that check for ex.reason to look like this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ALL) { ... } if (ex.reason < 0) { ... } ~~~ This is a preparation step for running a script that converts all TRY_CATCH uses to look like this instead: ~~~ TRY { ... } CATCH (ex, RETURN_MASK_ALL) { ... } END_CATCH ~~~ The motivation for that change is being able to reimplent TRY/CATCH in terms of C++ try/catch. This commit makes it so that: - no condition other than ex.reason < 0 is checked in the if predicate - there's no "else" block to check whether no exception was caught - there's no code between the TRY_CATCH (TRY) block and the 'if (ex.reason < 0)' block (CATCH). - the exception object is no longer referred to outside the if/catch block. Note the local volatile exception objects that are currently defined inside functions that use TRY_CATCH will disappear. In cases it's more convenient to still refer to the exception outside the catch block, a new non-volatile local is added and copy to that object is made within the catch block.

Introduce interpreter factories If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

Move "tee" building down to interpreter::set_logging_proc This patch gets rid of this hack in mi_set_logging: /* The tee created already is based on gdb_stdout, which for MI is a console and so we end up in an infinite loop of console writing to ui_file writing to console etc. So discard the existing tee (it hasn't been used yet, and MI won't ever use it), and create one based on raw_stdout instead. */ By pushing down responsibility for the tee creation to the interpreter. I.e., pushing the CLI bits out of handle_redirections down to the CLI interpreter's set_logging_proc method. This fixes a few leaks that I spotted, and then confirmed with "valgrind --leak-check=full": [...] ==21429== 56 (32 direct, 24 indirect) bytes in 1 blocks are definitely lost in loss record 30,243 of 34,980 ==21429== at 0x4C29216: operator new(unsigned long) (vg_replace_malloc.c:334) ==21429== by 0x62D9A9: mi_set_logging(interp*, int, ui_file*, ui_file*) (mi-interp.c:1395) ==21429== by 0x810B8A: current_interp_set_logging(int, ui_file*, ui_file*) (interps.c:360) ==21429== by 0x61C537: handle_redirections(int) (cli-logging.c:162) ==21429== by 0x61C6EC: set_logging_on(char*, int) (cli-logging.c:190) ==21429== by 0x6163BE: do_cfunc(cmd_list_element*, char*, int) (cli-decode.c:105) ==21429== by 0x6193C1: cmd_func(cmd_list_element*, char*, int) (cli-decode.c:1913) ==21429== by 0x8DB790: execute_command(char*, int) (top.c:674) ==21429== by 0x632AE6: mi_execute_cli_command(char const*, int, char const*) (mi-main.c:2343) ==21429== by 0x6329BA: mi_cmd_execute(mi_parse*) (mi-main.c:2306) ==21429== by 0x631E19: captured_mi_execute_command(ui_out*, mi_parse*) (mi-main.c:1998) ==21429== by 0x632389: mi_execute_command(char const*, int) (mi-main.c:2163) ==21429== [...] ==26635== 24 bytes in 1 blocks are definitely lost in loss record 20,740 of 34,995 ==26635== at 0x4C29216: operator new(unsigned long) (vg_replace_malloc.c:334) ==26635== by 0x61C355: handle_redirections(int) (cli-logging.c:131) ==26635== by 0x61C6EC: set_logging_on(char*, int) (cli-logging.c:190) ==26635== by 0x6163BE: do_cfunc(cmd_list_element*, char*, int) (cli-decode.c:105) ==26635== by 0x6193C1: cmd_func(cmd_list_element*, char*, int) (cli-decode.c:1913) ==26635== by 0x8DB7BC: execute_command(char*, int) (top.c:674) ==26635== by 0x7B9132: command_handler(char*) (event-top.c:590) ==26635== by 0x7B94F7: command_line_handler(char*) (event-top.c:780) ==26635== by 0x7B8ABB: gdb_rl_callback_handler(char*) (event-top.c:213) ==26635== by 0x933CE9: rl_callback_read_char (callback.c:220) ==26635== by 0x7B89ED: gdb_rl_callback_read_char_wrapper_noexcept() (event-top.c:175) ==26635== by 0x7B8A49: gdb_rl_callback_read_char_wrapper(void*) (event-top.c:192) One is fixed by transfering ownership of the log file to the tee.

Introduce interpreter factories If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

Introduce interpreter factories If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

Make the intepreters output to all UIs When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

Convert observers to C++ This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

Emit inferior, thread and frame selection events to all UIs With this patch, when an inferior, thread or frame is explicitly selected by the user, notifications will appear on all CLI and MI UIs. When a GDB console is integrated in a front-end, this allows the front-end to follow a selection made by the user ont he CLI, and it informs the user about selection changes made behind the scenes by the front-end. This patch addresses PR gdb/20487. In order to communicate frame changes to the front-end, this patch adds a new field to the =thread-selected event for the selected frame. The idea is that since inferior/thread/frame can be seen as a composition, it makes sense to send them together in the same event. The vision would be to eventually send the inferior information as well, if we find that it's needed, although the "=thread-selected" event would be ill-named for that job. Front-ends need to handle this new field if they want to follow the frame selection changes that originate from the console. The format of the frame attribute is the same as what is found in the *stopped events. Here's a detailed example for each command and the events they generate: thread ------ 1. CLI command: thread 1.3 MI event: =thread-selected,id="3",frame={...} 2. MI command: -thread-select 3 CLI event: [Switching to thread 1.3 ...] 3. MI command (CLI-in-MI): thread 1.3 MI event/reply: &"thread 1.3\n" ~"#0 child_sub_function () ... =thread-selected,id="3",frame={level="0",...} ^done frame ----- 1. CLI command: frame 1 MI event: =thread-selected,id="3",frame={level="1",...} 2. MI command: -stack-select-frame 1 CLI event: #1 0x00000000004007f0 in child_function... 3. MI command (CLI-in-MI): frame 1 MI event/reply: &"frame 1\n" ~"#1 0x00000000004007f9 in ..." =thread-selected,id="3",frame={level="1"...} ^done inferior -------- Inferior selection events only go from the console to MI, since there's no way to select the inferior in pure MI. 1. CLI command: inferior 2 MI event: =thread-selected,id="3" Note that if the user selects an inferior that is not started or exited, the MI doesn't receive a notification. Since there is no threads to select, the =thread-selected event does not apply... 2. MI command (CLI-in-MI): inferior 2 MI event/reply: &"inferior 2\n" ~"[Switching to inferior 2 ...]" =thread-selected,id="4",frame={level="0"...} ^done Internal implementation detail: this patch makes it possible to suppress notifications caused by a CLI command, like what is done in mi-interp.c. This means that it's now possible to use the add_com_suppress_notification function to register a command with some event suppressed. It is used to implement the select-frame command in this patch. The function command_notifies_uscc_observer was added to extract the rather complicated logical expression from the if statement. It is also now clearer what that logic does: if the command used by the user already notifies the user_selected_context_changed observer, there is not need to notify it again. It therefore protects again emitting the event twice.
